IMPROVEMENT IN TIRE-MACHINES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, SAMUEL. Ron, Jr.,ofBoonville, county of Cooper, State 'of Missouri, have invented a newand usefullmprovement in Tire-Shrinkers, of which the following is afull, clear, and exact description, reference being had tothe'accompanying drawing making part of this specification, in whichh l-igure 1 is a perspective view of my improved mac me.

Figure 2 represents the operating-lever.

My invention relates to a novel construction of the operating-lever ofatire-shrinker, and a new arrangement of parts, whereby certainadvantages are obtained, as will be fully explained.

In the drawing A A A A are the posts, of which each pair are connected,at their upper ends, by the girts B B, substantially in the manner shownin the drawingi Each of these girts is provided upon its innerverticalface with a longitudinal groove extending from end to end.

In the drawing these girts are represented as being composed of twoparts, the lower'one of which is formed inone piece with the legs orposts A A, the

upper one being rebated upon its lower inner edge, said rebate forming,in combination with the lower part, the groove or way above referred to.

The lower lips or flanges of these grooves'are wider than the upper onesare, and project further in'toward the center, thus making the spacebetween the lower flanges at b narrower than the space between the upper ones at I), (see fig. 1,) for a purpose which will hereinafter beexplained.

G C are clamps, each provided with upright ears orlngs at such distanceapart as will admit of a wagontire being readily placed between them.

a c are small blocks, made preferably of steel and harddened. The upperfaces of these blocks are serrate e D D are wedge-shaped keys, fittingperforations or sockets in the upright ears of clamps (J C.

The clamps O C are provided with wings or flanges, 0, adapted to fitclosely and more freely in the grooves in the girts B B.

The clamp C is rigidly'seoured in position at one end of girts B B,while the clamp G'is free to slide in the groove when actuated bydevices which will be presently described.

E is a forked lever, the upper arm 0 being expanded to a width aboutequal to the width of clamp O.

The lever E is connected with the stationary clamp (l by means of apivoted link or links, E, substantially asshown in the drawing, thelength of these links being such that when the parts are in workingposition, as shown in the drawing, the clamp O abuts against the broadend c of lever E.

F is a spring, the free end of which rests against the inner side ofclamp G.

The lever is confined to the body of the clamp by the machine'is readytorepeat the operation.

, It will be seen that by my manner of arranging the lever andconnecting-links the power is applied directly tothe clamps and theframe-Work relieved of all strain, and also that by making the upper armof v the forked lever of greater width than the space be tween the lowerflanges of the girtsB B, these flanges are made to form a support, uponwhich the inner end.

of the lever rests in a convenient position for operating.

When preferred the girts B B may be made of one piece each, and groovedby machinery or otherwise.

It will be seen that as lever B is pivoted to the free ends of links IEit (the lever) is movable vertically, and can be adjusted relative tothe clamp 0., against'which the end e bears, and hence can be so appliedas to operate the clamp with but little or no friction upon the ways, orof the end 0 upon the face of the clamp, while at the same time thelever is practically adjustable relative to clamp O G, as follows: I I

It sometimes happens that a single sweep of the lever will not shorten athe quite as much as is desired, and in such a case I can withdraw thelever a little, and, by inserting a suitable block between the end a andthe clamp, still further shrink it, the inserted block serving as agauge to indicate the amount of this shrinkage.

The expanded'end e serves not only to form a wide bearing upon theclamp, but also to support the inner end of the lever upon the flangesI), thus keeping it (the lever) always in a convenient position forwork-Having now described my invention,

\Vhat I claim as new, and desire to secure by Letters Patent, is-

The combination of the clamps O 0, links F, lever B, ways B B, andspring F, all constructed and operating as described.

In testimony whereof I have hereunto set my hand this 6th day of August,A. D. 1870.
